Bel knorvn that ?,,FnaNi F. LANDIs,v a -'citiz"en' of the Unit-ed States, residing at ayneshoro, in the county of Franklin and Stateof Pennsylvania, have invented certain new and useful Improvements in Conveyors,

of which the following is'a specification.v

'1 In the use of-conveyers of that general construction shown in my former patent, No. 61l,383j, -Wherein the conveyer-sections are nountedu on the same shaft with the blastan oi-disc arg'er; thief-speed of the shaft re- (ci uired to enable'the "dischar er to properly I 9 its Workisbftentiines muc h greater than is necessary for'the hestcperationof said conveyer section's. The resultis that the blades .do not take m'the material as readily and '.-'evenly as-when run'more slowly and are :einore {likely to break and grind said material. .=.My said invention consists; therefore, in a constructionof such conveyor whereby said ditlicn'lty-is obviated, I :Seidimprovements relate particularly to Qthe construction or the convcyer-sections 2 with single arms,j each arranged upon a hub and mounted on the shaft, the arms of the several sections projecting alternately from opposite sides of the shaft, whereby a c onveyer is provided'Wit-h only one-half the num ber'of arms and their contact with and grinding effect upon said material thus greatly reduced' and the entrance of the material into said conveyer facilitated, all as will be presently more fully described and claimed.

which are made a art hereoi and on which similar reference c aracters indicate similar parts, Figure 1 is a section through the dis charger and conveyer casings at the rear end of the threshing-machine separator, arranged to receive the straw from the straw-rack, the conveyer-sections being shown in elevation; Fig. 2, a front elevation (if one of said sections separately; Fig. 3, a detail cross-section on the dotted line 3 3 in Fig. 2; Fig. 4, a View similar to a-portion of Fig. 2, showing the hub with the counterbalance-weight removed; and Fig. 5, a view of said counterbalance-weight and the set-screw for securing the same separately.

In said drawings the portions marked A represent the conveyercasing, B the discharger, and O the conveyer-sections. The casing A, discharger B, thedischarger-casing 55 B, in which said discharger is mountdflon- Specification of Lttersl-"atent. Application filed August 30,1 04. Serial at. 221,4 3.

gitudinal' shaft 1, and drivingpulley 2 are all of a well-known and common construction andarra'ngement, as shown in my patent shove referred, to, and-need no further description herein.

Theconveyensections are of the number required for the particular use for which the conveyor is designed and are mounted at suitable intervals onshatt 1; 1 Each consists of a curvedarm mounted upon 9i? hub G, which has an eyeadapted ,toiit 'upon theshaft 1.

Each of said. 'armaextends-for a distance radially from said hulojkheing curved forward someWhat,- and exten s outwardl from the center a distance Winch Will bring its outer edge into close proximity to the surface of the V casing n.

It then extends spirally in a forward direction toward the discharger endof said casing, its dutside edge being curved to correspond substantially with the curvature of said casing, so that said edge will run near thereto to its end. Each arm thus embraces about one-quarter of a circle or" the diameter of said casing, and the several arms being arranged to extend alternately from the opposite sides of the shaft the material. delivered from the duter end of one arm will be in position to be taken up and carried forward by the rear portion of the next arm, and ample open space for the receipt of the material 18 provided between said arms.

. In order to secure an even and satisfactory operation of such conveyor, I find that it is necessary to have the balanced upon the shaft, not only in relation to each other; but that each arm shall be balanced in itself. I therefore provide for each arm a counterbalance-weight C, having a grooved recess in its front face adapted to slide upon transversely-extending Wings or flanges 0, formed,

on the hub opposite to said arm and ind in s with the centerofgravity thereof in both di rections, as shown most plainly in Figs. 1 and- 2. Said weight C is secured in p ition by means of of the set-screw c whichextends through a screw-threaded perforation in said weight and projects thro gh a perforation in the hub and impinges against the side of securing the Weight to the hub and the hub and its conveyer arm'in the desired position on said shaft.

shaft l thus serving the double purpose of f Each of said arms is provided with a stiffening-flange c on its rear side extending from the hub out .Wardly a sufficient distance tor the purpose,

also with a strengthening-web 0 extending on the front side at the base of said arm. Each of said arms is thus mounted upon the shaft in a perfectly-balanced condition in all directions and an even and uniform operation thus assured. In eneral the arrangement and operation are su stantiallythe same as in my patent above referred to, except that by, reason of the improvements above described Iam enabled to run the shaft at a very high 1 rate of speed to secure the best result from discharger B without impairing the effective-- ness of the conveyor, the arms being so widely separated that even at a high'rate of speed the will take in the straw and other material wit out difficulty and convey it to the-discharger with ample s 'eed.

Having thus fully escribed my said invenby Letters Patent, is-

1. -A conveyer comprising a casing, a drivtion, what I claim as new, and desire to secure ing-shaft having a discharger upon one end,

conveyersections I arran ed at intervals throughout its length, eac of said sections consistin of a hub and a sin le arm curved from sai hub, first substantia ly at right anthereon, eac ofsaid conveyer-sections consistmg of a hub havin an outwardly-curved spiral arm projecting om one side thereof, saidsections being arranged with their adja- 'weight to said hub and said section'to s ai cent arms projecting from the shaft in different directions, substantially as set forth.

4. A conveyer-section comprising a hub carrying an outwardly and forwardly curved arm upon one side thereof, and acounterbalance-weight upon its opposite side in line with the'center of gravity of said curved arm, substantially as set forth.

5. In a conveyer, the combination of a shaft, conveyer-seotions mounted thereon,

each comprising a hub having, a conveyerarm formed on one side and-projectin substantially at right angles with the sha t and then'in a spiral direction, a counterbalanceweight mounted opposite the center of gravity of said. arm, and a set-screw for securing-said shaft, substantially'as set forth.

6. A conveyercomprising a conveyer-casing and shaftmounted thereon, a diseharger mounted on the outer end of said shaft in 'a discharger -casing, said discharger-casing communicating with said conveyer-casing, a series of. conveyer-arms mounted on said shaft each bein formed to extend in a direction substantia ly at ri ht angles with the shaft for a distance an circle from the center of the shaft forwardly, and a counterbalance-weight located on the opposite side of said shaft in a line with the center of ravity of said arm, substantially as set forth.

In-witness whereof I have hereunto set my hand and seal, at Washington, District of Columbia, this 25th day of July, A. D. 1904.
